PURPOSE: To improve the durability and visibility in the rain and at night by coating a road surface with a coating material composed of quick dry solvent free reaction hardenable resin of high durability in dots at desired intervals and forming semispherical dots having predetermined diameter and height. CONSTITUTION: The color paint 1 for daytime is applied to the road surface A with a desired width when necessary after the sediment is swept off. Then the quick dry solvent free reaction hardenable resin coating material such as acryl, epoxy, polyester and polyurethane is prepared. The coating material is applied on the paint 1 at constant intervals or at random to form the convex semispheres of 5-50 mm diameter D and 2-10 mm of height H. Further the glass beads are scattered in the semispheres 2, and hardened and fixed when necessary. Whereby the impairing of retroelection performance and the sliding resistivity can be prevented for a long period, and the visibility in the rain and at night can be further improved. |
